Warnings/content: Jacob being obsessive, smut, Charlie pop up, Jacob being Jacob
(Twilight AU in which Jacob isn't in love with Bella and actually imprinted on Bella's younger sister aka y/n.)
Being Bella’s younger sister came with its own quiet rhythm of pros and cons. The pros were simple, almost sacred in their familiarity..Bella understood you. She never pushed you to be louder, never made you feel strange for preferring the soft hum of rain on the roof to a crowded party.
She got the whole quiet, kept-to-yourself thing because, for most of your lives, that’s exactly how she was too. You shared a language of comfortable silences, of knowing glances across the dinner table, of twin souls content in the shadowy, evergreen gloom of Forks.
Then came the con. His name was Edward Cullen.
You hadn’t trusted him from the first moment you saw him at school with Bella, something in his too perfect stillness, the way his golden eyes seemed to look through people rather than at them. Now, you knew why. He was a vampire. And his very existence had, like a stone thrown into a still pond, sent ripples of danger crashing into your once-peaceful lives. Other vampires, ancient, hungry, and vengeful, now saw you and Bella as targets. All because of him. Yeahhh… thanks, Edward. the sarcasms a thin shield against the genuine fear that now lived in your gut.
The front door slammed, jolting you from your thoughts. You looked up from the couch to see Bella frantically shoving her arms into her coat, her movements jerky with anxious energy.
“Hey, uh..I’ll be back tomorrow! Tell Charlie I left a note on the counter!” she called out, not even meeting your eyes.
“Good talk,” you murmured to the empty space she left behind, the words swallowed by the sound of her truck engine roaring to life. She was a ghost in her own home these days. You couldn’t decide if she was trying to run from Forks or if she was forever chasing a certain brooding, pale figure deeper into the Olympic forest.
A quiet sigh escaped you as you turned back to the television, the remote clicking monotonously as you flipped through a blur of infomercials and static. The living room felt too big, too empty. That’s when you felt it, a subtle shift in the worn quilt draped over your legs. You glanced down.
A familiar head of dark, tousled hair emerged from beneath the blanket, followed by a pair of warm, mahogany eyes and a smile so cheeky it could only belong to one person.
Jacob Black had made himself at home, his head now a comfortable, undeniable weight on your thighs. His large, warm hands found your sides, his thumbs tracing slow, deliberate circles against the fabric of your sweater. “What’s the matter, princess?” he rumbled, his voice a low vibration you felt more than heard. “You look bored. And you’re thinking too loud. Smells like… frustration and Cullen-induced anxiety in here.”
“You know,” you said, trying to keep your voice even, “if my dad walks through that door and finds his daughter on the couch with a guy lying all over her, hidden under a blanket, he’s going to go straight for the gun safe. Just a heads-up.” You tilted your head, your eyes darting toward the front door as if expecting Chief Swan to materialize on cue.
Jacob’s smile didn’t falter. “Ah. Excuse me,” he huffed, feigning offense. “I’m not just a ‘guy.’ I’m your boyfriend. A little hurt there, y/n.” He squinted up at you, the playful glint in his eyes belying his wounded tone.
“When,” you groaned, letting your head fall back against the couch cushion, “did we ever have the ‘you are my boyfriend’ talk?” You reached down, not unkindly, and tangled your fingers in the thick silk of his hair, giving a gentle tug of annoyance.
He went very still. The easy humor drained from his face, replaced by a look of such genuine, wounded disbelief it made your stomach clench. “Don’t come at me with that bullshit,” he said, his voice losing its playful rumble for something sharper. “What’s that supposed to mean?” In one fluid, surprisingly graceful motion, he sat up, turning to face you fully. The blanket pooled around his waist, and the sheer size of him, the focused intensity of his gaze, made the spacious room feel suddenly very small.
“We never said anything about dating,” you shrugged, trying to sound nonchalant, leaning further back as if you could escape the gravity of his presence. “That’s all I’m saying.”
“We never said anything about *not* dating,” he shot back, frustration simmering beneath the words. His jaw was tight.
“I’m just saying,” you pressed on, your own frustration rising to meet his. “You can’t just… claim me. Not because of this whole… weird wolf thing you have on me-”
“I imprinted on you,” he corrected, the words heavy and final.
“Yeah, yeah, let me speak,” you sighed, tiredly shaking your head. “You can’t immediately decide what we are just because you have this.. this supernatural pull or whatever. It’s unorthodox. It doesn’t feel like a choice.”
He scoffed, a harsh, unhappy sound. “Ah. Yeah. Okay. Thanks for clearing that up for me. No big deal, then.” Sarcasm dripped from every word. “I’m only around you 24/7. I only spend every waking moment making sure you’re safe, that you’re fed, that you’re smiling, all because I think of you as a friend. Seriously?” He ran a hand through his hair, the gesture agitated. “Listen, I can’t help that I’m literally, biologically, soul-deep obsessed with you. The imprint… it’s not a choice for me either. But what I feel for you? That’s real. That’s all me.”
Before you could respond, he laid back down, his head returning to your thigh with a defeated thump. His arms wrapped around your waist, his grip possessive and tight, as if he was afraid you’d vanish. The heat from his body seeped through your clothes.
“Oh,” he added, his voice dropping to a low, intimate murmur against your thigh. His earlier smirk found its way back, but it was softer now, tinged with a vulnerability that disarmed you. “And let’s not forget about the amazing nights I give you… or is sex meaningless to you, too, baby doll?” He tilted his head to look up at you, his eyes dark and knowing. “Ah… I’m hurt.”
Your face, which had been a mask of tired resolve, instantly flooded with heat. A traitorous flush crept from your neck to your cheeks, memories of those “amazing nights” appearing in your head. You looked away, but it was too late. He’d seen it.
A slow, genuine smile spread across his face, chasing away the last of his frustration. He nuzzled his cheek against your leg, his earlier tension melting into contented affection. “That’s what I thought,” he murmured, his voice a satisfied hum. “You can call it whatever you want, princess. Imprint. Fate. Werewolf aphrodisiac. But you feel this, too. And I’m not going anywhere.” He closed his eyes, his breathing evening out, as if the entire argument had simply been a temporary storm, and he was already home, anchored securely in your harbor.
You shifted uncomfortably under his gaze, the heat of his body pressing into you like a living furnace. Jacob's words hung in the air, that smug certainty wrapping around you tighter than his arms. He wasn't wrong..you did feel it, that pull, that undeniable spark that ignited every time he touched you. But admitting it out loud? That was a bridge you weren't ready to cross, not with the imprint hanging over everything like some cosmic decree.
Before you could muster a retort, Jacob's hands slid up your sides, his fingers hooking into the waistband of your sweatpants with deliberate intent. His eyes locked onto yours, dark and unyielding, a predatory glint flashing through them. "You wanna play games with labels, princess? Fine. But I'm gonna remind you exactly why you don't need 'em." His voice was a low growl, laced with that cocky edge that always sent a shiver racing down your spine.
"Jake-!" you started, but he cut you off with a firm shake of his head, his grip tightening as he tugged your pants down in one swift motion, exposing your bare skin to the cool air of the living room. No underwear, lazy evening habit that now left you vulnerable under his stare. He tossed the fabric aside, his large hands immediately parting your thighs, settling his broad shoulders between them like he owned the space.
"Shh," he murmured, his breath hot against your inner thigh as he nuzzled closer, inhaling deeply. "You smell like you need this. Wet already, aren't you? Thinking about all those times I've made you scream my name." His lips brushed the sensitive skin there, teasing, not quite touching where you ached most. That possessive rumble vibrated through him, his fingers digging into your hips to hold you still.
Your breath hitched, a protest dying on your lips as his mouth finally descended. His tongue flicked out, flat and broad, licking a slow, deliberate stripe up your slit, tasting you from entrance to clit. The sensation hit like lightning, hot, insistent, pulling a gasp from your throat. Jacob hummed in approval, the sound sending vibrations straight to your core. "Fuck, yeah," he muttered against you, his words muffled as he dove in deeper, his tongue circling your clit with expert pressure.
He wasn't gentle about it. Jacob ate you out like a man starved, his lips sucking hard on your swollen nub while his tongue thrust inside you, mimicking what he'd do with his cock later. One hand slid up to pinch and roll your nipple through your sweater, the dual assault making your back arch off the couch. You tangled your fingers in his hair again, not pulling him away this time, but urging him on despite yourself.
"That's it, baby," he growled between licks, his free hand spreading you wider, two thick fingers pushing into your pussy without warning. He curled them just right, hitting that spot that made stars burst behind your eyelids. "Feel how you're clenching around me? This pussy knows who it belongs to. Not some bullshit imprint..it's you wanting my mouth, my fingers, my everything."
The pressure built fast, his cocky words fueling the fire as much as his actions. He sucked your clit harder, fingers pumping in and out with wet, obscene sounds that filled the room. Your thighs trembled, squeezing his head, but he didn't let up, his grip bruising as he held you open for his assault. "Come on, princess. Come for me. Show me how much you need this."
You quickly came with a loud cry, your body convulsing as waves of pleasure crashed over you. Jacob didn't stop, his tongue lapped at you through it, drawing out every spasm, fingers still thrusting deep until you were a quivering mess. He pulled back just enough to watch your face, lips glistening with your arousal, that triumphant smirk firmly in place. "One down. But we're not done. Not even close."
Before you could catch your breath, he was back at it, his mouth relentless. This time, he focused on your entrance, tongue fucking into you while his thumb rubbed firm circles over your oversensitive clit. The overstimulation bordered on too much, your hips bucking involuntarily, but Jacob pinned you down with his weight, his free hand splaying across your stomach. "Stay still," he ordered, voice rough with desire. "I'm gonna make you soak this couch before I let you up. Prove to you that you can't run from this. From us. From me."
His fingers joined his tongue again, three this time, stretching you as he scissored them inside, hitting every nerve. He alternated sucking your clit with long, dragging licks, building you up again with that unyielding rhythm. Sweat beaded on your skin, the room spinning as the second orgasm ripped through you harder than the first. You moaned his name, loud, broken..your walls fluttering around his fingers as you gushed against his mouth.
Jacob groaned, lapping it all up like it was his reward, his cock straining against his jeans but ignored for now. He was focused, possessive, determined to wring every drop of doubt from you. "Look at you, coming undone for me again. That's my girl. Mine." He kissed your thigh, nipping the skin lightly before returning to your core, slower this time, teasing your clit with feather-light flicks until you were begging.
"Jake, please... I can't-" But you could, and he knew it. His tongue delved deep once more, fingers thrusting in tandem, his other hand slipping under your sweater to knead your breast, pinching the nipple until it ached. The third build was torturous, drawn out, his eyes flicking up to watch you writhe. "Yes, you can. One more, princess. Give me one more, and I'll fuck you senseless after. Show me you're as hooked as I am."
It hit like a tidal wave, your body seizing as you screamed, pleasure bordering on pain in its intensity. Jacob finally eased off, kissing your trembling thighs as you came down, his arms wrapping around you once more. He pulled you into his lap, your head against his chest, his erection pressing hot and hard against your ass. "Told you," he whispered, cocky satisfaction dripping from every word. "No labels needed when your body's screaming the truth. But if you want me to stop pretending... just say the word. I'm yours, y/n. All in." His hands stroked your back, warm and grounding, the storm of tension between you shifting into something deeper, more undeniable.
His words lingered, heavy with that cocky promise, as his hands roamed your body, slipping under your sweater to shove it up and over your head. The cool air hit your bare skin, but Jacob's heat chased it away immediately, his mouth latching onto your breast. He sucked hard on your nipple, teeth grazing the peak while his tongue swirled around it, drawing a fresh moan from your lips. You were still sensitive from before, every touch amplified, but you didn't push him away, instead, your fingers dug into his shoulders, holding him closer.
"See?" he murmured against your skin, switching to the other nipple, biting down just enough to make you gasp. "Your body's begging for more. No more bullshit about what we are." He pulled back, eyes dark with hunger, and yanked his shirt off in one fluid motion, revealing the sculpted planes of his chest and abs, skin flushed and warm. His hands fumbled with his jeans next, shoving them down along with his boxers, his thick cock springing free, hard, veined, the tip already leaking pre-cum.
You couldn't help staring, heat pooling low in your belly again despite the exhaustion tugging at your limbs. Jacob noticed, of course, that smug grin spreading as he gripped your hips and lifted you effortlessly, positioning you over his lap. "Gonna fuck this doubt right out of you, princess," he growled, rubbing the head of his cock along your slick folds, coating himself in your arousal. He didn't wait for permission..thrusting up hard, burying himself to the hilt in one brutal stroke.
The stretch burned so good, your pussy clenching around his length as you cried out, nails raking down his back. He groaned, head falling back against the couch, but his grip on your ass was ironclad, guiding you down to meet every inch. "Fuck, you're tight. Always so fucking perfect for me." He started moving then, hips snapping up in a relentless rhythm, his cock pounding into you deep and fast. The couch creaked under the force, your breasts bouncing with each thrust as you rode him, chasing the friction.
One hand slid between you, his thumb finding your clit and rubbing firm circles, syncing with his thrusts. The dual sensation had you spiraling quickly, walls fluttering around him as the pressure built. "That's it, come on my cock," he demanded, voice rough, free hand squeezing your breast, pinching the nipple. You shattered again, orgasm ripping through you, pussy milking him as you soaked his lap. Jacob didn't stop..he just fucked you through it, grunting with the effort to hold back his own release.
He flipped you suddenly, laying you back on the couch with him looming over you, never pulling out. His weight pinned you down, cock driving deeper in this new angle, hitting that spot inside that made your vision blur.
"Round two," he panted, lips crashing against yours in a messy kiss, tongue thrusting in time with his hips. He broke away to suck on your neck, marking the skin with bites and bruises, possessive as ever. "Gonna fill you up soon, but not yet. Want you screaming again."
You wrapped your legs around his waist, urging him on, the earlier conflict drowned out by the raw need. His pace quickened, balls slapping against your ass with wet smacks, the room filled with the sounds of skin on skin and your shared moans. He reached down, fingers digging into your thigh to spread you wider, allowing him to grind against your clit with every plunge.
The build was slower this time, but no less intense, your body trembled, oversensitive, until you came again, harder, your pussy spasming so tight it nearly pushed him out.
Jacob cursed, pulling out just in time to stroke himself, hot ropes of cum painting your stomach and breasts. He collapsed half on top of you, breathing ragged, but his hand stayed between your legs, fingers sliding back inside your dripping pussy to keep you full. "Not done," he whispered, kissing your shoulder as he caught his breath. Minutes later, he was hard again, imprint perks, you guessed..and he rolled you onto your stomach, pulling your hips up.
"Ass up, princess," he ordered, slapping your cheek lightly before spreading you open. His cock nudged your entrance, then pushed in slow, savoring the way you arched and whimpered. He fucked you from behind now, one hand fisting your hair to pull your head back, the other rubbing your clit. The angle let him go deeper, stretching you around his girth, each thrust jolting you forward. "Feel that? Every inch is mine. You're mine."
You pushed back against him, meeting his rhythm, the third round blurring into a haze of pleasure. He leaned over you, chest to your back, biting your earlobe as he pounded harder. Fingers pinched your clit, rolling it until you were sobbing his name, orgasm crashing over you once more, your pussy gushing around him, drenching his thighs. Jacob followed this time, thrusting deep and holding, flooding your insides with his cum, hot and thick.
He stayed buried inside you, both of you panting, his arms wrapping around your waist to pull you flush against him as he softened. The living room smelled of sex, the couch a mess beneath you, but Jacob just nuzzled your neck, content. "Told you I'd go all night," he murmured, cocky even in exhaustion.
But then, headlights pierced the windows, the rumble of Charlie's cruiser pulling into the driveway. Jacob froze. "Shit," he whispered, pulling out carefully, cum leaking down your thighs. He grabbed the blanket, tossing it over you both as he scrambled for his clothes, shoving them on haphazardly.
The front door creaked open moments later. "Y/N? You still up?" Charlie's voice echoed from the hall, keys jingling.
"Yeah, Dad! Just... watching TV," you called back, voice shaky, pulling the blanket tighter around your naked form. Jacob smirked, mouthing 'close call' as he ducked behind the couch, silent and still. Your heart raced, the afterglow shattered, but the heat in his eyes promised this wasn't over, not by a long shot.
